I am a hobbyist in electronics with knowledge of circuits and fabrication. But lacking knowledge about this topic. I would be greatful if some one answers my silly questions mentioned below.
Today we have ample LED,s available in 1 watt, 3 watts and 5watts in "star" package with different optics. I recently bought a 1watt x 3 LED's fitted in a spot light enclosure. A driver is also supplied with that which connects to the 220 volts power source.
My question is when a LED can be lit with a series resistor to a DC or battery source, why we require a driver to drive the same? What is the advantage of using a driver? What is the function of a driver?
If i am intending to make a driver for 3watt Star LED, which will power it with 220 volts, How can i move ahead? Are there any reference designs or links?
What is the difference between a regular SMPS DC power supply and a LED driver? Can a SMPS power supply be used in place of a LED driver? If yes, How? and if no why?
Thanks lot...Neha
